Interesting.
The suggested amount in the UK was around the equivalent of 4 euros which equals around six Aussie dollars.
Fifteen bucks is huge,,,, perhaps you have some "company men" in your cong.
Jonahstourguide, I also found that interesting. The letter read to our congregation, in the US, specifically referred to combining two separate arrangements, the GAA and TOAA. Whereas, the letter I read online, written on London letterhead, only referred to the GAA.
So it appears they are not requesting the traveling overseers assistance arrangement (TOAA) in the UK.
